Description
Stop Bits. This bit specifies the number of stop bits transmitted with each serial character.
0: One stop is bit generated (Default).
1: If the data length is set to 5 bits via bits [1:0] (WLS[1:0]), 1.5 stop bits are generated. For
Character Length Select [1:0]. These bits specify the number of data bits in each trans-
mitted or received serial character.
00: 5 (Default)
01: 6
10: 7
11: 8
EPS
6-, 7- or 8-bit word lengths, 2 stop bits are transmitted. The receiver checks for 1 stop bit
only, regardless of the number of stop bits selected.
